Purpose

Plugin for 2D and 3D non-negative, iterative, deconvolution. Based in part on the DAMAS algorithm by Thomas F. Brooks and William M. Humphreys, Jr., NASA-Langley Research Center. Also includes a regularized Wiener filter as a preconditioning step. Called DAMAS3 in aeroacoustics.

Documentation

The plugin was also the subject of a conference paper:
Dougherty, R. (2005), "Extensions of DAMAS and Benefits and Limitations of Deconvolution in Beamforming", 11th AIAA/CEAS Aeroacoustics Conference (26th AIAA Aeroacoustics Conference)
.

Version 4: 6/3/2005. Corrected a scaling error in the iteration. Provided an option to turn off the Wiener filter. Added divergence detection. Changed the defintion of the low pass filter parameters (multiplied by 2) to better match Iterative Deconvolution.

Version 5: 6/3/2005. Corrected a bug in the low pass filter in the z direction.
